Chlorophyll in the chloroplast reflects green color on the spectrum of

visible light.

What is chlorophyll?

Each pigment has a distinctive absorption spectrum that illustrates how it absorbs or reflects various light wavelengths. Chlorophyll and other pigments used in photosynthesis absorb wavelengths, creating electrons that power photosynthesis. All visible light wavelengths, with the exception of green, are absorbed by chlorophyll, the green pigment found in all photosynthetic cells. Because of this, plants seem green to us.

Hence, Chlorophyll in the chloroplast reflects green color on the spectrum of visible light.

The number of Atlantic puffins that have adapted to species A will decrease as competition for species A increases. After several generations, the puffins that eat species B and C will be formed.

Adaptation is the process of changing in response to a changing environment. An example is seen in puffins. The puffin that eats species A has a different beak. When another predator enters who preys upon species A, then competition will increase. As a result, species A's consumption of puffin will decrease.

Those puffins that eat species B and C will survive. They will reproduce and produce more offspring. The number of puffins with beaks in Species B and C will increase over time.

Hence, after many generations, puffins of species B and C will increase.

The term "restriction fragment length polymorphism" (RFLP), which stands for individual changes (or variants) in DNA sequences at locations identified by restriction enzymes.

Botstein et al. (1980) created restriction fragment length polymorphisms (RFLPs), which employ restriction enzymes to cleave the DNA molecule at particular locations known as restriction sites, producing various fragments with varied lengths.

Restriction One technique for studying DNA used by forensic scientists is fragment length polymorphism (RFLP). The DNA strand is divided into pieces during this procedure by an enzyme. One restriction is that it struggles with dirt or mold.

Drift genetic provides a mechanism for evolution.

Option A is correct.

The variety of known evolutionary change-causing mechanisms has been substantially expanded by genetics. Most of these mechanisms are non-selective or even counter-selective, but they all involve converting variation between individuals into variance across populations over time and place.

The study of evolutionary genetics focuses on how genetics affects the course of evolution. The evolution of genomic structure is being studied in this context. It consists of population genetics and evolution combined. Genome evolution is the process by which the genome's size and structure evolve over time.

The molecular basis of non-infectious diseases is associated with the organism's response to genetic and environmental diseases that are not spread among suitable hosts.

The expression non-infectious diseases is broad and it includes all types of diseases that are not spread among individuals in any type of environmental phenomena. These types of diseases are multifactorial since they are caused by both environmental and genetic factors.

For example, cardiovascular diseases and obesity are non-infectious diseases caused by environmental factors (e.g. consumption of salt in the case of cardiovascular diseases or fat in the case of obesity), and also by certain genetic factors that increase the risk form suffering these diseases.

Therefore, with this data, we can see that non-infectious diseases are associated with both genetic and environmental factors and they are not spread as occurs with infectious diseases caused by viruses and bacteria.

The coelom refers to the body cavity derived from mesoderm germ layer and mainly found in multicellular animals and is positioned inside the body to surround and contain the digestive tract and other organs.

There are many advantages that coelom provides to the earthworm and the salamander. The digestive system of earthworms and salamanders is more complex, here coelomic fluid helps their body processes and assists as a hydrostatic skeleton.

The coelom's main advantage is its flexibility. The internal organs for example the heart, liver,  lungs, and intestines develop, and they help to push into the coelom. The fluid of the coelom diminishes the organs for protecting the organs and also enables them to turn, bend, shift and move. In this way, coelom helps the animals internally to finish and run the system inside in the correct way. Coelom helps the earthworms and salamanders in building the correct system and protecting their organs to maintain and enable them to function properly.

The lytic cycle includes the replica of viruses using a number cellular to fabricate greater viruses; the viruses then burst out of the cellular. The lysogenic cycle involves the incorporation of the viral genome into the host cellular genome, infecting it from inside.

Inside the lytic cycle, the viral genome does no longer comprise into the host genome. within the lysogenic cycle, the viral genome consists of into the host genome and stays there throughou The main difference among lytic cycle and lysogenic cycle is that lytic cycle destroys the host cell while lysogenic cycle does no longer spoil the host mobile

The primary difference between lytic cycle and lysogenic cycle is that lytic cycle destroys the host cell whereas lysogenic cycle does not destroy the host cell.

RBC’s make up about 84% of cells in the body, but they are only 4% of body weight. Whereas, 75% of total weight are fat cells and muscle cells. They’re both large cells but constitute only a minute fraction of the total number of cells.

How many cells is the human body made of?

The exact number of cells is still debatable. But to put it briefly, around 30-40 trillion. The long answer? Not yet determined.

What we do know, is that RBC’s (red blood cells) make up the majority of cells in our bodies. They make up only 4% of total mass, despite constituting 80% of all cells. The reason is that RBC’s measure 8 micrometers in diameter.  The size of fat cells, however is around 100 micrometers.

The total number of cells to this date is still not defined, but we have a slight idea of what could be.

Therefore, the reason for RBC’s having 84% of cells and 75% of fat cells is their mass. RBC’s are only 4% of total weight because their measure is only 8 micrometers. Whereas fat cells are around 100 micrometers in diameter.

Sickle cell disease (SCD) is a genetic disorder caused by a mutation in the gene that codes for hemoglobin, a protein responsible for carrying oxygen in red blood cells.

The mutation results in the production of an abnormal form of hemoglobin known as hemoglobin S (HbS). Sickle cell disease is inherited in an autosomal recessive manner, meaning that an individual must inherit two copies of the mutated gene (one from each parent) to develop the disease.

Effects at a Protein Level:

Hemoglobin normally has a rounded shape, allowing red blood cells to flow smoothly through blood vessels. However, in sickle cell disease, the abnormal hemoglobin S causes red blood cells to become stiff and take on a crescent or sickle shape under certain conditions, particularly when oxygen levels are low.

Effects at a Cellular Level:

The sickle-shaped red blood cells are prone to clump together, leading to the formation of blood clots. These clots can block blood vessels, causing a reduction in blood flow to various organs and tissues.
